Terrace, Shadow, and Cliff Lakes Trail

Terrace, Shadow, and Cliff Lakes Trail is a 3.4-mile out-and-back from the signed Terrace Lake turnout on Lassen Peak Highway. It drops about 650 feet from an 8,000-foot start into cirques below Reading Peak, visiting Terrace Lake, Shadow Lake, and Cliff Lake before returning along the same line. Allow about three hours with time at the water. Published totals vary: the mapped line and trail signs support about 1.7 miles each way, while a separate route description still gives 4 miles. Use 3.4 miles for planning and leave some extra time rather than rushing.

The trail drops quickly through hemlock woods. After 0.2 mile, the left fork heads toward Hat Lake; take the right branch to Terrace Lake. The first lake is small, and the route climbs briefly away from it before descending toward Shadow. Continue along Shadow's south shore, then follow the trail through open woods and meadow for over half a mile to the Cliff Lake junction. The final branch crosses a low moraine to the lake. Turn around there; this is an out-and-back, not a loop.

The mileage sounds modest, but the route loses about 650 feet on the way in and makes you climb it back after the lakes. The high starting elevation matters, especially if you are not used to hiking near 8,000 feet. The park rates the hike moderately strenuous and advises trekking poles for the steep downhill toward Shadow; poles can also help on the climb back. Parts of the route are sun-exposed, and the tread has uneven rocks and roots. The north-facing slopes can hold snow later than lower park trails, so check current road and trail conditions before driving in.

The three lakes sit in cirques below the north side of Reading Peak. Terrace has clear water and a rocky, forested edge where the cliffs can reflect on a calm day. Shadow is the largest; from its western side you can look toward Lassen Peak. Beyond it, the forest opens into meadow before the Cliff Lake branch, where pale, boulder-strewn slopes frame a shallower shoreline. The final leg changes the walk again: there is more open sky, a moraine crossing, and a more rugged basin feel than at the first lake.

The main payoff is seeing three distinct alpine lakes in one walk rather than reaching a single summit or waterfall. Late-summer flowers can make the shoreline and meadow worth a closer look; a late-September field report noted tundra asters by Terrace Lake, though blooms vary from year to year. For photos, calm water at Terrace can mirror the cliffs, while the west side of Shadow gives the clearest Lassen Peak backdrop. Keep a little foreground shore or trail in the frame so the picture reads as a place in the basin, not just blue water.

You can make this shorter by turning back at Terrace Lake, about 1 mile round trip, or Shadow Lake, about 1.6 miles round trip. Both options keep the steep initial descent and uphill return but skip the extra open stretch and final moraine to Cliff. The full route earns its added effort if you want all three lakes and have time for the longer climb back. Start at the signed roadside turnout; parking is limited, and there is no developed lot at the trailhead. Pets are not allowed on park hiking trails. The seasonal cafe at Kohm Yah-mah-nee Visitor Center is a separate stop near the southwest entrance, not a service at the turnout.
